STM32 USB Mass Storage Class issue

[Red_Micro]

I'm testing the STM32 USB MSC using FATFS. I'm using two different flash drives, one generic 128GB and one 8GB encrypted. When using the 128GB one, things work well. See picture "generic.PNG". However, with the encrypted one, I get fatal error. When the stack resets the USB port, then the device stops responding. This encrypted flash drive works well in any computer that I connect it to. I just enter the password via the hardware keypad and that's it. Does anyone know about the issue I could be facing? I would expect the encrypted flash to be more problematic obviously but I'd like to understand if I need to set up things differently on the STM32 end to make it work.

I see you also posted this question on the STM32 forums and ST said they'll contact you directly. Hopefully they can help.

The ST code for USB MSC, and FatFS, is nothing to do with encryption. It is just implementing a block device.

Where is the encryption done?
